            Bug ID: 260891
           Summary: failing test case:
           Product: Base System
           Version: CURRENT
          Hardware: Any
                OS: Any
            Status: New
          Severity: Affects Only Me
          Priority: ---
         Component: tests
          Assignee: testing@FreeBSD.org
          Reporter: rew@FreeBSD.org

The failing test:


With error message:

/usr/src/lib/libnv/tests/nvlist_send_recv_test.c:457: nvl != NULL not met

I *think* the problem with this test is that the nvlist_send() fails because
the underlying sendmsg() call fails with ENOBUFS. Then, nvlist_recv() returns
NULL because it detects that it didn't receive the expected number of file

Adjusting net.local.dgram.recvspace worked on local machine, however, on CI the
test still fails consistently.

I'll disable this test for now.
